long tubes like the ARH (American racing headers), Kooks long tubes or Doug Thorley tri-ys. The SLP headers aren't a "true" long tube header, they're more lime a mid-length one like the Kooks mid-lengths or "shorty" header.

Either way, if you do headers of any sort you will have to get a different tune. The Cortex can't handle the headers and you will constantly trip a code until you have a proper tune.

One reason why I don't have headers currently. . Though I will be getting a different G8 once my lease is up. I like the black but I just don't have the time to do it justice.

I set my superchips to 50% torque for the winter months. Tranny shifts too hard at the 100% value and causes wheel slip. At 75% sometimes I slip a little going into 2nd gear in the rain. This transmission wakes up like you wouldn't believe when tuned. I logged a 5.0sec 0-60MPH with my superchips to 75% on a not so good road with some sand still on it and the crappy stock Eagle RSAs.

I got my Superchips in the other day, All set up with the stock tune logged inside. This weekend looks great! so I think I am going to mess around with it then. To change the Trans. Torque you need to go into Advanced tune correct? Some of this stuff it tricky.

Yeah, it's really simple actually. What I would do first is plug it into your computer and update it. They've tweaked the tunes quite a bit and improved the options/performance.

Once you tune for a specific octane, you then can plug into your PC and pull down an intake specific tune.

But yes, advanced tuning options is where you want to go. I usually set shift torque to 50% or 75% as this is my DD, raised rev limiter, Superchips shift points for all gears, and speed limiter off.
